Generally they are only controlled by the flap handle. The only exception is the autoslat system. The LE flaps, which are inboard of the engines, come out all the way whenever the flap handle is not up. The LE slats come out "partial" when the flap handle position is greater than zero, but less than or equal to 5. When the flap handle is greater than 5 the slats come out all the way. The autoslat system is only active when the LE slats are in the "partial" position. If the airplane approaches a stall the autoslat system will cause the slats to come out all the way. If the limit airspeed for flaps 40 is exceeded they will blow back up to the 30 position. This feature only exists for the flaps 40 position. > Ideally, what I'd like is to know for each flap handle setting, the > deflection in degrees of the leading and trailing edge flaps. I would guess only Boeing knows that. All I know is that at the lower-numbered flaps settings you get mostly flap translation, and at the higher-numbered positions you get mostly deflection. > * A 737 takes off somewhere in the world every 5.3 seconds. Reminds me of O'Hare.
